Think about the concentration of reactants and products: When Q > K, the concentration (or activities) of products increase (numerator increases) causing the rxn to make more reactants

Re: When to use H vs H2

I also have a question: when you have a reaction in the form of MgSO4.7H2O where the 7 is in front of the H2O, would you have to do 7x(molar mass of H2) + the molar mass of O or 7x(the molar mass of H20)?
